I just made my first blog last week, it's self hosted: http://www.theworldisabook.co.uk
Things were going fine and I set my theme as Pilcrow, then I was in the middle of installing a new theme yesterday (called Origin if I remember correctly), when I got this error message:
Fatal error: Call to undefined function wp_get_theme() in /home/thewo456/public_html/wp-content/themes/origin/library/functions/utility.php on line 119
This now comes up whenever I try to access the dashboard or actual site... On my iPad I can still see the home page of my dashboard but as soon as I try to go any further (e.g. onto plugins, or updating my version of wordpress) I get a very similar error message:
Fatal error: Call to undefined function wp_get_theme() in /home/thewo456/public_html/wp-content/themes/origin/library/admin/theme-settings.php on line 35
I have no idea what to do as I literally can't access anything so any suggestions would be much appreciated!
